Title: Method for forming ink jet image
Inventor: IRIHARA KOICHI
IPC: B41J2/01
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To solve a problem that image deterioration due to lowering of a printed density and a change of hue when a fast-drying ink is printed as a background in order to reduce a drying time for a slow-drying black ink. SOLUTION: When the slow-drying black ink and the fast-drying black ink are used at the same time, a printing rate of the slow-drying black ink is not less than 67%. When the printing rate of the slow-drying black ink is not less than 67%, the printing density is always greater than 1.20 irrespective of the fast-drying black ink (YMC) printed as a background so that it is possible to obtain roughly the same density as in the printing only by the slow-drying black ink. That is, when the printing rate of the slow-drying black ink is not less than 67% (the printing rate of the fast-drying black ink is not greater than 33%), it is possible to obtain the sufficient printing density. In this case, the change of hue hardly occurs compared to the printing only by the slow- drying black ink.  In the case where the fast-drying black ink is printed as a background in order to reduce the drying time of the slow-drying black ink, the printing rate of the slow-drying black ink is set to be not less 67% and then it is possible to suppress the deterioration of the image quality due to the lowering of the density and the change of hue as little as possible.
